TIRE.

To all whom it may concern: y

Be it known that l, GEORGE F. FISHER, a citizen of the United States,residin at Roselle, county of Union, and State of ew Jersey, haveinvented certain new and useful Improvements in Tires, o f which thefollowing is a. full, clear, and exact description.

T his invention relates to tires of that' nfeneral class in which theedges are conliiied against stretching by inextensible restrainingmembers. Usually tires of this type are completelybuilt upon a sectionalcore` and after vulcanization of the tire the sections of the core aredisassembled and removed from the tire. `By the present invention tiresof .this'typeare built upon a solid core, thus promoting economy inlabor, and in vthe' amountv of tire "material which enters into thetire.

In carrying Aout the invention, the tire is 'built on a solid core tocomprise plies `of Vmaterial :that jpass over 'thetread of the core andextend approximately to the edges thereof. The ltire is then vulcanized,and after vulcanizat-ion it is stripped from the fcore asis done at.present wii elencher tires. Inoxtensible restraining members for thevedges `are now secured outside of the vulcanized plies to complete theformation of the tire.

The invention ean-be readily understood from the following -descriptiontaken in connection with the accompanying drawing, in which- Figure l isa cross-sectional View showing a tire embodying my'improvements.

Fig. 2 is a fragmentary slde elevation of vthe t1re.

Fig. 3 is a detail perspective view -of one of the restraining members.y

Fig. 4 is a fragmentary sectional view of a modified form of theinvention.

In the embodimentpof the invention illustrated the tire is built upon asolid, that is, a non-sectional ring core, (not shown) to comprise pliesof material .10. All of the lies are of such width that the tirs` willbe slightly larger than ordinarily at it.. inner diameter, that is, atthe edges which come next to the vehicle wheel rim,by an amount equal tothe thickness of the inextensiblerestraining members hereinafterdescribed, so that a saving of tire material is promoted. At this stagethe tire is vulcanized, in any Speccationiof Letters Patent. Patented:MaJ- 5, 1918 Application filed April 14, 1916.

Serial No. 91,005.

- gered elements 12 connected together by a bar 13, the elements beingprovided with prongs 14. The restraining members are applied astride, ofrespective edges of the tire and the` prongs forced to penetrate .theplies and firmly secure the members in position. The ends of cachrestraining member 'are brought vto'getler and are preferably welded orotherwise united tovp'roduce an inextensible annulus.

If desired, each restraining member may be left exposed, but I prefer`:to'eonceal them by covers 15, preferably l,of the 'same material lasVthe plies, and which may be cemented or otherwise secured to 'theplies.

A modified form of the invention 1s shown in Fig. 4 wherein' each edge-portion of the, vulcanized tire is reinforcedwith an endless bead wire16 composed ofa number of convolutions of wire, and disposed -outside ofthe plies to lie along the .inneredge thereof. Preferably each bead wireis anchored to the edge of the wire by means of a restraining membersuch as above described, which is` placed astride of the bead wire as'shown, and firmly anchors the same in place.-

-While I have describedand illustrated one l specific embodiment of theinvention, I do not limit myselfltothe exact construction disclosed,since a wide range of nrodiica'v tions may be resorted to within thescope of the appended claims without departing" 1ovo I claim 'asnew anddesire to protect by Leif ters. Patent is:v

1. yA tire embodying e plurality of strips of woven fabric vulcanizedtogether to form plies 'of the tire with the free ends of the threadscomposing the strips terminating at the edges of the tire, and arestraining inem ber ac jacent szid edges exteriorly thereof having ribsprojecting therefrom on either side 0f the tire provided 'with pointed.prongs embedded in the plies 'formechanically securing the tire andrestraining member together.

2. A tire embodying e plurality of strips of woven fabric vulcanizedtogether to form plies of the tire with the free ends of the threadscomposing the strips terminating at the edges of the tire, arestraining-member adjacent said edges exteriorly thereof,and

a fastenin device embracing seid member and extent ing up the tire onboth sides and provided with ointed prongs embedded in the pliesof saitire.

A tire embodying a plurality of strips of woven fabric. vulcanizedtogether to form plies of the tire with the free ends of the threadscomposing the strips terminating at the ledges of the tire, a.restraining member adjacent said edges exteriorly thereof, a asteningdevice embracing said member and extending up the tire on both sides,and means for securing said device to the tire, said means penetratingseid Woven plies at a relatively considerable distance aboveihe freeends of the threads.
